【 摘 要 】

This investigation affords a novel work in four-dimensional (4-D) reconstruction of the Nepal Earthquake deformation the usage of interferometry synthetic aperture radar (InSAR). To this end, the established InSAR techniques are carried out to two repeat passes of Sentinel-1 an images data. Additional, the four-dimensional phase unwrapping is carried out the usage of Flynn's algorithm, four-dimensional best-path avoiding singularity loops (4- DBPASL) algorithm and Pareto ant colony algorithm. The results expose that the Pareto ant colony algorithm achieved precisely in contrast to Flynn's algorithm, four-dimensional best-path avoiding singularity loops (4-DBPASL) algorithm. In conclusion, assimilation of the Pareto ant colony algorithm with 4-DBPASL phase unwrapping produce precisely 4-D surface distortion owing to Nepal earthquake.
